At first, a pail contained
25 ℓ of water. Jane added another
14 ℓ of water into the pail. Then she used
313 of all the water in the pail. How much water did Jane use? Express your answer as a fraction in its simplest form.
Total volume of water in the pail after Jane added more water into the pail
= 25 + 14
= 820 + 520
= 1320 ℓ
13 u = 1320
1 u = 1320 ÷ 13 = 1320 x 113 = 120
Volume of water that Jane used
= 3 u
= 3 x 120
= 320 ℓ
Answer(s): 320 ℓ
